web项目访问jsp路径 Servlet及相关类和接口(4)

5、GenericServlet类

先看源码：

package javax.servlet;

import java.io.IOException;
import java.io.Serializable;
import java.util.Enumeration;

public abstract class GenericServlet implements Servlet, ServletConfig,
        Serializable {
    private static final long serialVersionUID = 1L;
    private transient ServletConfig config;

    public void destroy() {
    }

    public String getInitParameter(String name) {
        return getServletConfig().getInitParameter(name);
    }

    public Enumeration<String> getInitParameterNames() {
        return getServletConfig().getInitParameterNames();
    }

    public ServletConfig getServletConfig() {
        return this.config;
    }

    public ServletContext getServletContext() {
        return getServletConfig().getServletContext();
    }

    public String getServletInfo() {
        return "";
    }

    public void init(ServletConfig config) throws ServletException {
        this.config = config;
        init();
    }

    public void init() throws ServletException {
    }

    public void log(String msg) {
        getServletContext().log(getServletName() + ": " + msg);
    }

    public void log(String message, Throwable t) {
        getServletContext().log(getServletName() + ": " + message, t);
    }

    public abstract void service(ServletRequest paramServletRequest,
            ServletResponse paramServletResponse) throws ServletException,
            IOException;

    public String getServletName() {
        return this.config.getServletName();
    }
}
